One mole of an ideal monatomic gas undergoes a cyclic process as shown in the figure. The total heat supplied to the gas is :
Answer: (C) $600$ J
For a complete cycle, $\Delta U = 0$, so the net heat supplied equals the net work done by the gas:
$$Q = W$$
The cycle $a \to b \to c \to d \to a$ is traversed clockwise on the $P$-$V$ diagram, so the work is positive and equals the enclosed area:
$$W = (300 - 100) \times (5 - 2) = 200 \times 3 = 600\ \text{J}$$
Total (net) heat supplied $= 600$ J.
